The annual Food Shopping Trends Tracker survey conducted for the country's most expensive grocer, Whole Foods, said 51 percent of Americans are eating at home more often and 37 percent are holding tight to strict grocery budgets.

The survey surprisingly shows that 76 percent of organic and natural food shoppers still want the same quality food. (Not that surprising since the study was commissioned by Whole Foods. )

"We recognize that shoppers should be able to cut costs, not corners when buying natural and organic foods," A.C. Gallo, co-president and chief operating officer for Whole Foods Market, told the Business Times. "This research is in sync with what we are seeing right now with our customers."
